herzogone just to throw this out there. The snowboard addiction videos helped me tremendously to ride boxes and rails This year I'm stepping up the rails a bit. There are tons of great tips/information I would never have known on my own nor found out the hard way. Being a dad of similar situation, this was a HUGE help for me to ride safer and better in the park.
You may want to check them out if you haven't already.
Not saying I haven't slammed by any means, just a lot less had I not known what to do....
